Starbucks offers free coffee to good citizens

On Tuesday, Schultz announced that anyone who paid for another customer's favorite drink Wednesday through Friday, the good citizen would receive a free tall brewed beverage.

"Faced with this seemingly unending cycle of dysfunction and doubt, it would be understandable if many of us -- and our customers -- felt cynical, powerless or disengaged," Schultz writes in an open letter on the Starbucks website. "So, as we have done in the past, we once again find ourselves asking a simple question: What can WE do about it at Starbucks? After all, we're just a coffee company."
